        Well, from the sounds of it this has as much in common with rockets as it has with said spam. A rocket isn't "something that has expanding gas" or "something that uses hydrogen peroxide". A rocket is a device for producing thrust by ejecting propulsion mass. "Piston powered" would be more like it.

          It is piston driven, but there is a connection bto rocket power. The catalyst and high-test peroxide fuel mechanism were first developed for rocket propulsion (and are still used in astronaut backpacks for maneuvering).

          So it isn't literally rocket powered but it is rocket technology powered.

        • It may use steam, but as it's not made of brass nor is it powered by coal or lamp oil, I say, it's not steam punk enough. It didn't even say users need to wear goggles, big brass goggles.
      • This is a steam powered artificial limb. It has nothing to do with rocket power (thrust produced by ejecting reaction mass) other than the fuel.
  • Rocket power sounds really keen, except it's extremely inefficient, like under 1%.

    Rocket exhaust is high-velocity, low thrust. For a mechanical arm, you need like 1/100th the velocity, and lots of thrust.

    In other words, rocket powered arms are like trying to drag race with your transmission in like 30'th gear.

        Yeah, but a steam engine works by steam created by boiling normal water with an external power source and using the pressure. This works by burning H2O2 which ends up producing steam and then this high-pressure steam is used. It's not external combustion. It's closer to an internal combustion engine, actually.

        I wouldn't call this a rocket, but it does seem to mix rocket engines (for high pressure gas generation) with steam engines (for harnessing high pressure gas). The closest thing I can think of is a car

          The term you are looking for is "Gas Generator".

          Rocket is something that generates gas (usually by combustion or decomposition) and expels it through a nozzle for thrust.

          Gas generator is generic for a device which produces gas. A boiler is a special case (heat + water). There are gas generators in airbags (solid azide chemical reaction), other industrial uses too.

          This just uses decomposing hydrogen peroxide to generate steam. Just another gas generator.

      Caption:
      A solid model of the arm shows how it works. The propellant cartridge contains the pressurized monopropellant. The liquid is routed through two flexible lines (not shown) across the elbow join and into two catalyst packs: one for the elbow and one for the foream. The catalyst increases the effective volume of the propellant by 1000 times. The propellant does not flow continuously but is controlled and routed by the servo valves just downstream. By rotating to different positions, a servo valve routes the gas to one side or the other of a gas cylinder, pusing the piston up or down. The entire operation is computer controlled, based on force and motion feedback from the joints.

      Hydrogen peroxide + catalyst = hot gas (steam)

    The Army prefers not to put powered vehicles on the front line because
    (1) they require refueling, and fuel is a supply/logistics problem, and
    (2) they make noise, and
    (3) being mechanical, they break.

    Loading up each soldier with enough H2O2 to get through the day would require stocking and maintaining equipment for this stuff. Running out of H2O2 before you can get refueled will result in removing the equipment so it won't detract from action, and that will result in soldiers abandoning it rather than run around burdened by something they can't use.

    Sitting around making a hissing noise makes one a target even in the dark.

    Putting a non-combatant like a mechanic/armorer on the front line is a bad idea because they can get killed, leaving you with useless armor. If this happens, or if it breaks and you don't send a mechanic/armorer because they're a burden themselves, it will result in the same abandoning noted above. Electrical devices break down less than mechanical and make them more likely to be adopted and used.

    If H2O2/catalyst devices are capable of producing sufficient power, they'd be being developed for use in fuel cells (which still requires the rear line placement), which could recharge battery powered armor (which doesn't have near the other problems). To be efficient it would require high purity stuff, which is hard to produce, and requires difficult and expensive maintenance no matter how far back it's made and stored. Even so, it'd be better from a logistic and tactical stand point to develop hydrogen based fuel cells to charge battery powered armor, running off the hydrogen from the fuels they're already going to be carting around -- unleaded, diesel and JP4/8.
